1 They do their best work at 55ÂºF, but can carry on right down to 0ÂºF. As they eat away at organic materials, they give off a small amount of heat.  Mesophilic - Second wave of microbial activity. Most of the decomposition in a compost pile is mesophilic.
In general, it is thought that implants last approximately 10 years or should be replaced every eight to 10 years. A ruptured saline implant is clinically obvious as the breast will deflate and there will be great asymmetry. A ruptured silicone implant is more difficult to determine and is referred as a silent rupture.
Numbness after an implant procedure is the result of nerve disturbance / irritation during the placement procedure. It can also be caused during administration of local anesthesia if the needle touches the main nerve branch (this type is temporary and usually resolves in 6-8 weeks). The degree of nerve disturbance from implant placement and how long the numbness will last depends on the type of nerve injury. If mild and very superficial, it usually resolves in 6-8 weeks. If moderate, then partial or almost complete return of sensation may happen up to 9 months. If severe injury, then it may be long term or permanent numbness.
